Definition - What does H-1B Visa mean?
The H-1B visa is an employment-based non-immigrant visa in the United States that allows companies to employ foreign workers in specialty occupations on a temporary basis. An H-1B visa is issued for a period of three years. It can be extended to six years. A specialty occupation is defined as one that requires practical or theoretical expertise in a field of study. There is a minimum qualification of a bachelor's degree in that field.
Justipedia explains H-1B Visa
In order to be granted an H-1B visa, an individual must demonstrate an employer-employee relationship with a potential U.S. employer. Authorization for the H-1B visa is strictly limited to employment by the employer sponsoring the visa. The H-1B is the preferred choice of companies who wish to bring workers to the United States for long term assignments. The procedure is easier and faster than applying for a green card. It is also one of the most preferred visas for individuals who wish to get their green card in the future because the H-1B is one of the few visa categories in the U.S. that is recognized as dual intent.
